-bearing layers from the upper Carboniferous period. The coal seams reach the surface in a strip along the river Ruhr and dip downward from the river to the north. Beneath the Lippe, the coal seams lie at a depth of 600 to 800 metres (2,000 to 2,600 feet). The thickness of the coal layers ranges from one to three metres (three to ten feet). This geological feature played a decisive role in the development of coal mining in the Ruhr.
According to the Regionalverband Ruhr (RVR, Ruhr Regional Association), 37.6% of the region's area is built up. A total of 40.7% of the region's land remains in agricultural use. Forests account for 17.6%, and bodies of water and other types of land use occupy the rest. The inclusion of four mainly rural districts in the otherwise mainly industrial Ruhr helps to explain the large proportion of agricultural and forested land. In addition, the city boroughs of the Ruhr region have outlying districts with a rural character.
Seen on a map, the Ruhr could be considered a single city, since—at least in the north–south dimension—there are no visible breaks between the individual city boroughs. Thus the Ruhr is described as a polycentric urban area, which shares a similar history of urban and economic development.
Because of its history, the Ruhr is structured differently from monocentric urban regions such as Berlin

Industrial revolution
The development of the region into an urbanized industrial area started in the late 18th century with the early industrialisation in the nearby Wupper Valley in the Bergisches Land. By around 1820, hundreds of water-powered mills were producing textiles, lumber, shingles and iron in automated processes here. And in even more workshops in the hills, highly skilled workers manufactured knives, tools, weapons and harnesses, using water, coal and charcoal. History has no established name for this phase of the industrial revolution, but one could call it the early water-powered industrial revolution.
As the machines became bigger and moved from water power to steam power, locally mined coal and charcoal became expensive and there was not enough of it. The Bergische industry ordered more and more coal from the new coal mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from ...
area along the Ruhr. Impressive and expensive railways were constructed through the hilly Wupper region, to bring coal, and later steel, in from the Ruhr, and for outward transport of finished products.
By 1850, there were almost 300 coal mines in operation in the Ruhr area, in and around the central cities of Duisburg, Essen, Bochum and Dortmund. The coal was exported or processed in coking ovens into coke, used in blast furnace

Consequently, the population climbed rapidly. Towns with only 2000 to 5000 people in the early 19th century grew in the following 100 years to over 100,000. Skilled mineworkers were recruited from other regions to the Ruhr's mines and steel mills and unskilled people started to move in. From 1860 onwards there was large-scale migration from Silesia

and Posen to the Ruhr. Many of them were Polish speakers and they were treated as second class citizens. In 1899 this led to a revolt in Herne of young Polish workers, who later established a Workers' Union. Skilled workers in the mines were often housed in "miners' colonies", built by the mining firms. By 1870, over 3 million people lived in the Ruhrgebiet and the new coal-mining district had become the largest industrial region of Europe.
During World War I the Ruhrgebiet functioned as Germany's central weapon factory. At a big Essen company, F. Krupp A.G., the number of employees rose from 40,000 to 120,000 or more, in four years. They were partly women, partly forced labourers.

The Weimar government defeated the putsch, albeit it advocated a general strike, which large parts of the working class participated in. The general strike effectively ended the Kapp government, but in the Ruhr, striking workers successfully managed to take government buildings in March 1920 shocking the rest of Germany. An armed revolt was then instigated, and the Red Guard installed a branch in the Ruhr. This became known as the Ruhr Uprising. The workers councils that led the uprising declared the Ruhr to be a socialist republic, but the Freikorps and Reichswehr

In January 1923 the whole Ruhrgebiet was occupied as a reprisal after Germany failed to fulfill World War I reparation payments as agreed in the Versailles Treaty. The German government responded with "''passive resistance''", letting workers and civil servants refuse orders and instructions by the occupation forces. Production and transport came to a standstill and the financial consequences contributed to German hyperinflation and ruined public finances in Germany and France, as well as several other countries. Passive resistance was called off in late 1923, allowing Germany to implement a currency reform and to negotiate the Dawes Plan
The Dawes Plan (as proposed by the Dawes Committee, chaired by Charles G. Dawes) was a plan in 1924 that successfully resolved the issue of World War I reparations that Germany had to pay. It ended a crisis in European diplomacy following W ...
, which led to the withdrawal of the French and Belgian troops from the Ruhr in 1925. However, the occupation of the Ruhr caused several direct and indirect consequences on the German economy and government. Due to the lack of production caused by foreign occupation, the German economy lacked the domestic abilities to pay war reparations without intentionally causing inflation. Moreover, the government became increasingly unpopular due to its "passive resistance" to German production. The halt in domestic production made war reparations impossible to pay.

, containing much of Germany's remaining coal deposits, was handed over to economic administration by France as a protectorate in 1947 and did not politically return to Germany until January 1957, with economic reintegration occurring two years later. Parallel to the question of political control of the Ruhr, the Allies tried to decrease German industrial potential by limitations on production and dismantling of factories and steel plants, predominantly in the Ruhr. By 1950, after the virtual completion of the by-then much watered-down "level of industry" plans, equipment had been removed from 706 manufacturing plants in the west, and steel production capacity had been reduced by 6.7 million tons. Dismantling finally ended in 1951. In all, less than 5% of the industrial base was dismantled.

of the 1950s and 1960s, as very rapid economic growth (9% a year) created a heavy demand for coal and steel.
After 1973, Germany was hard hit by a worldwide economic crisis, soaring oil prices, and increasing unemployment, which jumped from 300,000 in 1973 to 1.1 million in 1975. The Ruhr region was hardest hit, as the easy-to-reach coal mines became exhausted, and German coal was no longer competitive. Likewise the Ruhr steel industry went into sharp decline, as its prices were undercut by lower-cost suppliers such as Japan. The welfare system provided a safety net for the large number of unemployed workers, and many factories reduced their labor force and began to concentrate on high-profit specialty items.
As demand for coal decreased after 1958, the area went through phases of structural crisis (see steel crisis) and industrial diversification, first developing traditional heavy industry, then moving into service industries and high technology.

The International Labour Organization (ILO) is a United Nations agency whose mandate is to advance social and economic justice by setting international labour standards. Founded in October 1919 under the League of Nations, it is the first and ol ...
published a report entitled ''Coal Production in the Ruhr District''. In 1923, the ''Canadian Commercial Intelligence Journal'', Volume 28, Issue 1013, includes the article, "Exports from the Ruhr district of Germany". In 1924 the English and American press was still talking of the "French occupation of the Ruhr Valley" or "Ruhr District". A 62-page publication seems to be responsible for the use of "Ruhr" as a short form of the then more common "Ruhr District" or "Ruhr Valley": Ben Tillett, A. Creech-Jones and Samuel Warren's ''The Ruhr: The Report of a Deputation from the Transport and General Workers Union'' (London 1923). Yet "The report of a deputation from the Transport and General Workers' Union which spent a fortnight examining the problems in the Ruhr Valley", published in ''The Economic Review'', Volume 8, 1923, is still using the traditional term. In the same year, "Objections by the United States to discriminatory regulations on exports from the occupied region of the Ruhr" was published in ''Papers Relating to the Foreign Relations of the United States''.
The 1926 ''Encyclopædia Britannica'', in addition to its article on the river Ruhr, has a further article on "RUHR, the name given to a district of Westphalia, Germany". Thus the name "Ruhr" was given to the region (as a short form of "Ruhr District" or "Ruhr Valley") only a few years before the publication of this edition of the ''Encyclopædia Britannica''. Even after World War II, the term "Ruhr" may not have been in general use for the region: it was defined in ''Documents on American Foreign Relations'' (1948): "For the purposes of the present Agreement: (i) the expression 'Ruhr' means the areas, as presently constituted, in Land North Rhine–Westphalia, listed in the Annex to this Agreement." However, Lawrence K. Cecil and Philip Hauge Abelson still write in 1967: "In the first place, the average person uses the term 'Ruhr' indiscriminately as the Ruhr River or the Ruhr district, two entirely different things. The Ruhr River is only one of half a dozen rivers in the Ruhr district, in addition to the Rhine. The Rhine itself runs through the heart of the Ruhr district." According to ''Merriam Webster's Geographical Dictionary'', a standard reference on place names around the world, the name "Ruhr" refers to the river. The name preferred for the region in this dictionary is "Ruhrgebiet", followed by "Ruhr Valley".

with influences from the various dialects found in the area and changing even with the professions of the workers. A major common influence stems from the coal mining tradition of the area. For example, quite a few locals prefer to call the Ruhr either "Pott", which is a derivate of "Pütt" (pitmen's term for ''mine''; cp. the English "pit"), or "Revier".

Originally the system was even bigger, it was possible to travel from Unna to Bad Honnef without using railway or bus services.
Road transport
The Ruhr has one of the densest motorway networks in all of Europe, with dozens of Autobahns and similar Schnellstraßen (expressways) crossing the region. The Autobahn network is built in a grid network, with four east–west (Bundesautobahn 2, A2, Bundesautobahn 40, A40, Bundesautobahn 42, A42, Bundesautobahn 44, A44) and seven north–south (Bundesautobahn 1, A1, Bundesautobahn 3, A3, Bundesautobahn 43, A43, Bundesautobahn 45, A45, Bundesautobahn 52, A52, Bundesautobahn 57, A57, Bundesautobahn 59, A59) routes. The A1, A2 and A3 are mostly used by through traffic, while the other autobahns have a more regional function.
Both the A44 and the A52 have several missing links, in various stages of planning. Some missing sections are currently in construction or planned to be constructed in the near future.
Additional expressways serve as bypasses and local routes, especially around Dortmund and Bochum. Due to the density of the autobahns and expressways, Bundesstraßen are less important for intercity traffic. The first Autobahns in the Ruhr opened during the mid-1930s. Due to the density of the network, and the number of alternative routes, traffic volumes are generally lower than other major metropolitan areas in Europe. Traffic congestion is an everyday occurrence, but far less so than in the Randstad in the Netherlands, another polycentric urban area. Most important Autobahns have six lanes, but there are no eight-lane Autobahns in the Ruhr.
